Abstract: PURPOSE: A method for saving power of a remote control system is provided to receive data in an initial 'on' state of a system to decide a communication speed, and to make a user directly set a turn-on/off time of an RF(Radio Frequency) unit, and the method enables the improvement of an algorithm deciding data and noise, to improve system efficiency. CONSTITUTION: If communication data are received, a communication speed is decided within a predetermined bit number received initially. A user decides a turn-on time of an RF(Radio Frequency) unit through an operating panel according to the decided communication speed, and stores the decided turn-on time in a memory of a micro computer. The user decides a turn-off time of the RF unit through the operating panel, and stores the decided turn-off time in the memory. Whether a remote control system is in a power save mode and the RF unit is turned on are decided. If the RF unit is turned on, the micro computer decides whether inputted signals are data or noise within the predetermined bit number inputted initially. If the inputted signals are noise, whether the turn-on time of the RF unit is ended is confirmed. If ended, the turn-on time of the RF unit is reset to the set value and a turn-on flag is cleared. If the RF unit is turned off, whether the turn-off time of the RF unit is ended is confirmed. If ended, the turn-off time of the RF unit is reset to the set value and a turn-on flag becomes on.
